Hertwich Engineering, which is part of SMS group and specializes in plant and machinery for the liquid phase of the aluminum production process, developed Ecomelt furnaces for recycling and melting aluminum scrap, whereby the scrap that is contaminated by paints or oils, for example, is burnt off, and the energy released is recycled and utilized. This reduces the demand for natural gas to a minimum and offers a double advantage for the plant owner. The extent to which aluminum is fed back into the production cycle is set to grow significantly in the years to come. Hertwich Engineering has just the right response to this trend with its highly advanced, energy-efficient recycling furnaces.
Nordural zero emissions project
In Iceland, Hertwich is taking part in a zero emissions project for the aluminum sector. Hertwich will supply two electrically heated holding furnaces, a vertical caster, and a continuous caster for an annual production of 120,000 tons of aluminum billets to Nordural. As a systems supplier, Hertwich will also implement the foundry’s automation system. The homogenizing plant to be supplied comprises a 100% ultrasonic tester, including a billet saw and strapping machine. By using electric power generated from renewable sources, the entire plant can be operated in a climate-neutral manner.
“We are proud to support Nordural in its goal of producing ‘low-carbon aluminum’. As a systems supplier and partner, we are jointly setting new standards for low CO2 emissions per ton of aluminum billets produced and, in doing so, we are making a significant contribution to hitting global climate targets”, explains Hertwich CEO Gerold Keune.
Nordural is part of Century Aluminium in the USA. With its strategic position between North America and Europe coupled with CO2-neutral power generation in Iceland, Nordural is able to offer its low-carbon Natur-Al brand of aluminum with shorter delivery times.
